A CORPORATION OF NEW JERSEY.

EDGE-INKING- MACHINE.

Specification of Letters Iatent. Patented July 29, 1919.

r Application filed lJecember 2,1915. Serial No. 64,706.

To all whom it may concern:

Be it known that I, v citizen of the United States, and resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Edge-Inking Machines, of which the following description,

in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for applying liquid to stock and is herein illustrated in connection with a machine for ap plying ink to the raw edges of pieces of upper leather which are to be used in the manufacture of boots and shoes.

In the manufacture of high grade shoes it is customary to skive and fold the margins of pieces of upper leather so as to produce finished edges. Onthe cheaper grades of shoes, however, it is sometimes customary to apply coloring matter, known in the trade as ink, to the raw edges instead of skiving and folding them. The machine of the present inventlon is an improvement upon the machine of my Patent No. 874,359 and is adapted to produce a more even application of ink than said patented machine and to prevent the ink from deteriorating through exposure to the air.

According to the present invention the ink applying member is a rotary perforated shell having a cover of absorbent material, and the ink is supplied in small regulated quantities to said material. With this construction the amount of ink carried by the absorbent material may be maintained substantially uniform so that the edges of pieces of leather presented to the applying member will receive substantially uniform applications of ink. In order to prevent the ink from deteriorating through exposure to the air of the applying member when the machine is idle, a cap is provided for covering the applying member'when not in use.

These and other features of the invention, together with certain details of construction and combinations of parts, will be described in connection with an illustrative machine and pointed out in the appended claims.

PERLEY R. GLAss, a

Referring to the accompanying draw- 1ngs,-

Figure l is an elevation of a machine in which the present invention is embodied, certain parts having been broken away to show the structure more clearly;

Fig. 2 is a detail perspective on an en larged scale showing the applying member in the process of applying ink to the edges of a bunch of tips;

Fig. 3 is a detail, principally in section, of the end of the outlet pipe, showing more particularlythe valve by which the flow of ink is regulated.

Mounted on the frame 1 of the machine is an ink receptacle 3 from the bottom of which leads an outlet pipe 5. A sleeve 7 rotatably mounted on said pipe carries at one end an ink applying member 9 and at the other end a beveled gear 11, said gear meshing with a small bevel gear 13 fastto a short shaft upon which a driving pulley 15 is mounted. The sleeve 7 also has fast to it a grooved pulley 17 around which passes a belt 19,said belt passing over idle pulleys, one of which is shown at 21, and around a pulley 23, said last named pulley being fast to the upper end of a spindle 25- to the lower end of which is fastened a stirrer 27. In the lower side of the outer end of the pipe 5 is an outlet hole 29 through which the ink flows at a rate determined by a valve 31 which is threaded into the end of the pipe so as to be capable of adjustment. In practice the ink is allowed to drip from the hole 29 into the interior of the applying member 9 as shown in Figs. 1 and 2.

The ink applying member 9 comprises a shell of frusto-conical shape having a cover of absorbent material 33, the forward end of said member having-an opening to permit access to the valve 31. Perforations 85 in the curved wall of the member 9 permit the ink to work through to and saturate the cover 33. The outer end of the member 9 is partially closed by a circular flange so that ink as used in the claims formed on a circular flange 37 of the frame a cylindrical seat to receive a cap 39 which, when it is in place, protects the ink upon the applying member from the action of the atmosphere.

In use, a bunch of parts of uppers, such for example as a 'bunch of tips 100, is presented to the member 9 in the manner illustrated in Fig. 2, the bunch of leather pieces being drawn across the face of the applying member 9.

As has been stated, thecoloring matter used in shoe factories for the purpose described is commonly called ink; and this term has been used in order to promote brevity. It should be understood, however, that the particular nature of the coloring matter used is immaterial and that the term is to be construed broadly.

Although the invention has been set forth in connection with a particular machine it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.

Having thus described my invention, I.

claim as new and desire to secure by Letters Patent of the United States:

1. A machine for inking the edges of pieces of leather, having, in combination, a reservoir for ink, an outlet pipe leading from said reservoir, a sleeve rotatably mounted on said pipe, and extending to a point adjacent to the outer end of said pipe, and an ink applying member fast to the outer end of said sleeve, said member comprising a perforated shell and a cover of absorbent material.

2. A machine of the class described having, in combination, a reservoir for ink, an outlet pipe leading from said reservoir, a valve in the outer end of said pipe, a sleeve rotatably mounted on said pipe and extending to a point adjacent the outer end of said pipe, an ink applying member fast to the outer end of said sleeve, said member com prising a shell having an opening in the end thereof to permit access to said valve and a cover of absorbent material, and means for rotating said member.

3. A machine of the class described, having, in combination, a reservoir for ink, an outlet pipe leading from said reservoir and having a portion slightly inclined to the horizontal, a valve in the lower end of said pipe, a sleeve rotatable on said inclined portion and extending to within a short distance from the end of the pipe, and an ink applying member fast to the end of said sleeve, said member comprising a frustoconical perforated shell and a covering of absorbent material.

4. A machine of the class described having, in combination, a reservoir for ink, an outlet pipe leading therefrom, an ink applying member mounted to rotate about said pipe and arranged to receive ink therefrom, and means for rotating said member, there being formed on the frame of the machine a seat for a cap which is designed to cover said member when said member is not in use.

5. A machine for applying ink to the edge of a piece of leather, having, in combination, a reservoir for ink, an outlet pipe leading from the reservoir, and an ink-applying member mounted to rotate about the pipe near the end thereof, said member compris ing a perforated shell and a cover of absorbent material the outer end of the shell being partly closed to prevent the escape of surplus ink which may be delivered through the p p 6. A machine for applying ink to the edge of a piece of leather, having, in combination, a reservoir for ink, a rotatable stirrer therein, an outlet pipe leading from said reservoir, an ink-applying member mounted to rotate about said pipe and arranged to receive ink therefrom, means for rotating said member, and connecting means between said stirrer and member whereby rotation of said member causes rotation of said stirrer.

7. A machine for applying ink to the edge of a piece of leather, having, in combination, a reservoir for ink, an outlet pipe leading from the lower part of the reservoir, an ink-applying member mounted to rotate about the pipe and to receive ink delivered through the pipe by gravity, and means for controlling the flow of the ink through the pipe, the ink-applying member com rising a perforated shell and a cover of absor entmaterial.

In testimony whereof I have signed my name to this specification.
